US Stocks Drop on Big Tech AI Spending and $100 Oil Fears

Traditional stock markets suffered a rough week as investors reacted to disappointing Big Tech earnings, surging oil prices, and massive swings in semiconductor shares. The Nasdaq fell roughly 2 percent between July 19 and July 25, while the S and P 500 dropped 0.6 percent and the Dow lost 0.4 percent. Technology shares faced the heaviest selling pressure as major companies reported high costs associated with artificial intelligence projects.

Tesla and Alphabet triggered a broad tech sell off after their updates raised concerns about high spending. Tesla shares dropped 14.5 percent following negative free cash flow, and Alphabet fell 7 percent after raising its expected capital spending. Meanwhile, Brent crude pushed above 100 dollars a barrel due to rising tensions between the United States and Iran. This energy spike renewed inflation fears, pushing Treasury yields higher and putting extra pressure on growth assets, including crypto.

Semiconductor stocks also experienced wild swings, bouncing between optimism for artificial intelligence demand and worry over heavy expenses. The Philadelphia Semiconductor Index jumped 5 percent early in the week before sliding 4.5 percent on Friday. Crypto markets felt the spillover from this risk off environment, as Bitcoin often trades alongside high growth equities when bond yields rise. Traders should watch macroeconomic data and upcoming tech earnings for signs of continued market volatility.
